style(cli): rebrand message markers with glyphs + portal chevron

Replace the ALLCAPS "SUCCESS:/NOTICE:/ERROR:/QUESTION:/OPTION:" prefixes
with distinct per-status glyphs and calmer title-case words:
  ✓ Success   ! Notice   ✗ Error   ❯ Question   ❯ Option
The portal chevron ❯ marks the interactive prompts. Distinct glyph + word
stays readable with no colour and greppable in logs. Display-only; nothing
parses these prefixes.
